"Money borrowed to fund the Slavery Abolition Act (1835) was therefore fully repaid in
2015. The long gap between this money being borrowed and its repayment was due to
the type of financial instrument that was used, rather than the amount of money
borrowed."

"Nathan Mayer Rothschild (1777-1836), a supporter of the abolition of the slave trade, played a role in a transaction which was significant in advancing the abolitionist cause. In August 1833, the British government led by the reformist Whig Earl Grey, passed the Slave Emancipation Act, giving all slaves in the British empire their freedom, albeit after a set period of years. Under the terms of the Act, slave owners received compensation for the 'loss of their slaves' in the form of a government grant; in contrast, enslaved people received no compensation. Compensation was abhorrent to abolitionists, such as Nathan, but under the leadership of Sir Thomas Fowell Buxton MP, enough came to accept it as a necessary evil in order to achieve the greater goal of the abolition of slavery."
